The buildout starts with a 100-megawatt facility in Ulsan targeting fourth-quarter 2027 operations, then scales to **5 gigawatts** of capacity by 2029 and a longer-term goal of 15 gigawatts nationwide. According to Yonhap, the initial 5-GW phase alone requires roughly **3 million GPUs** and 2.4 million HBM units, a scale that signals tightening near-term supply and longer lead times for accelerators and memory.

SKT will start with a 100-megawatt hyperscale AI data center in the port city of Ulsan, targeting operations by the fourth quarter of 2027, then add 900 megawatts plus a further 1 gigawatt elsewhere in the region. The company plans to reach 5 gigawatts of AI data-center capacity by 2029, which Jung called the first step toward a longer-term goal of 15 gigawatts nationwide. Jung said the initial 5-GW phase would require about 2,500,000 square meters of land, roughly 3 million GPUs, about 2.4 million HBM units, and around 350 trillion won in investment. "The massive AI data centers could transform the region into a hub for the verification and expansion of manufacturing AI, when combined with the manufacturing capabilities in the region," Jung said.48:["$","div",null,{"children":[["$","div",null,{"className":"article-summary mb-10","children":["$","div",null,{"className":"text-[20px] text-stone-800 leading-[1.6] font-serif font-normal","children":[["$","div","0",{"className":"mt-6 first:mt-0","children":[["$","p","0",{"className":"","children":["For ML infrastructure teams, this is a capacity-planning signal as much as a corporate announcement: a single operator committing to 5 gigawatts of AI data-center capacity by 2029, requiring an estimated 3 million GPUs and 2.4 million HBM units for the first phase alone, adds concentrated demand to an already tight global accelerator and memory supply chain.
